WiNeRF: Measurement Constrained Radiance Fields for Actionable Wireless Channel Modeling

WiNeRF is a neural field framework that learns a spatially continuous, complex-valued wireless channel representation from sparse channel state information collected by commodity WiFi devices. It incorporates system constraints such as antenna geometry, limited spatial resolution, and phase uncertainty through a 3D conical wave sampling model, a multi-resolution implicit scene representation, and a differentiable optimization framework. In diverse indoor environments with non‑line‑of‑sight regions, WiNeRF achieves a median prediction SNR of 5.3 dB, outperforming prior neural baselines by 4.9 dB on average, and produces a task‑agnostic channel representation that can be reused in standard signal‑processing pipelines without hardware or protocol changes.

Learning to Focus: CSI-Free Hierarchical MARL for Reconfigurable Reflectors

The paper proposes a CSI‑free hierarchical multi‑agent reinforcement learning framework for controlling reconfigurable reflective surfaces in millimeter‑wave networks. By replacing per‑element channel estimation with user localization data, the system uses a two‑tier neural architecture: a high‑level controller for discrete user‑to‑reflector assignments and low‑level controllers that optimize continuous focal points via MAPPO under a CTDE scheme. Deterministic ray‑tracing tests show RSSI gains of up to 7.79 dB over centralized PPO baselines and robust performance with sub‑meter localization errors for multiple users and reflector arrays.

Agentic Autoresearch for Cell-Edge Power Control: Radically Redefining the Researcher's Role

The paper presents an autonomous agent that designs machine learning algorithms for wireless power control, eliminating manual specification of architecture, loss, and training details. Using an autoresearch protocol, the agent iteratively edits a training script, runs experiments, and evaluates changes against a single metric, ultimately achieving 99.5% of a reference solution with vastly reduced inference cost. The agent’s discovered output parameterization matches the exact max‑min‑optimal allocation at the minimum percentile for all trained weights, demonstrating a principled, scalable approach to a complex, NP‑hard problem.
